apple tv not recognising home sharing with mac book air
Apple TV has worked fine in the past but now it is saying I need to turn on home sharing to find my computer. Home sharing is turned on my MacBook Air - nothing has changed since it last worked. I turned Apple Tv on and off again and tunrned home sharing on and off but still no go. Any advice appreciated.
